Procedure

To 175 mg (0.80 mmol) of N-[2-(trimethylsilyl)benzyl]cyclopropanamine in 5 ml of dry tetrahydrofurane was added 0.234 ml (1.68 mmol) of triethylamine, followed by a solution of 187 mg (0.88 mmol) of 5-fluoro-3-(difluoromethyl)-1-methyl-1H-pyrazole-4-carbonyl chloride in 3 ml of tetrahydrofurane. The reaction mixture was stirred under reflux for 3 hours. After cooling down, the reaction mixture was filtered, and the filtrate was evaporated under vacuum. The residue was dissolved in ethyl acetate/water. The aqueous phase was further extracted with ethyl acetate. The combined organic phase were dried and evaporated under vacuum to give 209 mg of the expected product.
